PUMP ATTACHMENT.

Application filed April 5, 1918. Serial No. 226,882.

' cation.

My invention is an improvement in pump attachments, and has for itsobject to provide an attachment of the character specified especiallyadapted for connection to an air pump of an automobile, in such mannerthat the pump will be operated by the turning of one of the .wheels, thewheel being jacked up for this purpose.

In the drawing Figure 1 is a side vlew of a portion of a motor Vehiclehaving the attachment;

Fig. 2 is a perspective View of the connecting means to the base of thepump;

Fig. 3 is a similar view of the clamp for the wheel, and,

Fig. 4 is a perspective View of the mechanism for connecting the pumprod to the clamp.

In the present embodiment of the inven tion, the pump comprises theusual cylinder 1, in which is movable a plunger operated by a plungerrod 2, which is provided at its outer end with a cross-head or handle 3.The base 4 of the pump is connected to the running board 5 of the motorvehicle, by means of the mechanism shown in Fig. 2.

This mechanism comprises a plate 6 having connected therewith asubstantially U- shaped clamp 7, one of the arms of the clamp beingsecured to the plate as shown,

while the other arm has threaded therethrongh a set screw 8.

The plate 6 is arranged on the upper face of the running board, as shownin Fig. 1, with the set screw 8' beneath the running board and when thescrew is turned, it will be evident that the plate will be clamped tothe running board. A second plate 9 is pivotally connected to the plate6 in spaced relation by means of a bolt 10. This bolt is passedtransversely through the plates 6 and 9, and is engaged by a nut 11 attheuopposite end from the head of the bolt.

The bolt has a, collar 12 between the plates to space them apart so thatwhen the plate 6 is clamped upon the running board, the plate 9 will befar enough away from the Specification of Letters Patent.

board to permit it to swing freely with respect to the plate 6. Thisplate 9 has an upstanding flange or rib 13 at the edge adj acent theplate 6, and at the other edge is a clamp 14 operated by aset screw 15.The base 4 of thepump is arranged between the rib 13 and the clamp 14,and by turning the set screw the base is clamped to the plate 9.

In Fig. 3 is shown mechanism for engaging the wheel. The said mechanismcomprises a substantially U-shaped bracket 16,

having threaded through one arm a set screw 17 and the other arm isprovided with a. laterally extending lug 18. The set screw has a saddle19 pivoted thereto, and this saddle is adapted to engage beneath the hubI 20 of one of the rear wheels 21, while the lug or lip 18 engages overthehousing of the hub between a pair of spokes andat a pointdiametrically opposite the saddle 19.- It will be evident that Whentheset screw is turned thle rilamp 16' will be firmly held to the w ee 1That arm of the clamp 16 which has the lip 18, carries also a plate 22,.which is held shown in Fig. 4. The said means comprises a clamp in theform of a plate24 which has at one end an angle lug 25 and at the othertwo hooks 26. A set screw 27 is threaded through the lug 25, and thisset screw has a pivoted saddle at its inner end. The plate 24 hasa'threaded stem 28 extending in the opposite direction to the lug andhooks, and this stem is adapted topass through one of the openings inthe plate 22, and to be en-.

cross head is arranged between the hooks and the saddle of the set screwwith the hooks engagmg the handle on the opposite sides of the plungerrod, and it will be noticed that the saddle is mid-way between the 110hooks. When now the set screw is turned, the plate 24 will be firmlyclamped to the cross head.
